[PATCH] ARM: dts: Remove "spidev" nodes

Rob Herring robh at kernel.org
Fri Dec 17 14:12:32 PST 2021


"spidev" is not a real device, but a Linux implementation detail. It has
never been documented either. The kernel has WARNed on the use of it for
over 6 years. Time to remove its usage from the tree.
